I've taken to not bothering to free anything in batch tools if it's not super-obvious what to do. Objects with a simple life time (including memory owned by a stack-local object such as a std::vector, etc.) get freed; everything else just leaks. You'd think this would cause masses of problems, but it doesn't. It's easy to imagine data that would be too large, but it seems to be rarer in practice than you might think. If the alternative is something like a handle-based or smart pointer system, then you'll reap the benefits in terms of ease of debugging on a daily basis.
